However, the world thus described is nothing but ours. All those who are familiar with the popularization of quantum physics are used to hearing these sentences, which fascinate and challenge. They often lead to the ideas, quite frustrating for the uninitiated, that quantum mechanics is a discipline full of paradoxes, and incomprehensible otherwise than by its mathematical formalism; and that even the best physicists disagree on what it means [1]}, [2]}.
Quantum mechanics being at the basis of innumerable technologies (electronics, lasers, medical imaging...) which have changed our daily life, and having never been disproved, this difficulty in communicating its physical content to the layman is surprising. It may even appear embarrassing, in a context where many countries are investing billions of Euros to develop technologies related to the “second quantum revolution", even more difficult to explain than the first one.
